Hydraulic test of plate heat exchanger
Thread Content
Gentlemen, regarding the hydraulic testing procedure for plate heat exchangers, in accordance with the manufacturing standard NB/T47004 for plate heat exchangers, a single-sided hydraulic test should be conducted on each side of the plate heat exchanger. When a hydraulic test is conducted on one side, the other side should simultaneously be in a pressure-free state. We currently have a machine for book processing: the operating pressure is 8 bar, the pressing pressure is 10.4 bar, and the maximum pressure difference is 8 bar. Is it possible to apply pressure to both sides simultaneously when the pressure exceeds 8 bar?
The operating pressure is 8 bar, the testing pressure is 10.4 bar, and the maximum pressure difference is 8 bar. Is it feasible to apply pressure to both sides simultaneously when testing at a pressure higher than 8 bar? === Understood at the beginning, confused later on
During normal pressure application, it is done one side at a time, whereas we apply pressure to both sides simultaneously at pressures above 8 bar
